Hmm, I'm not entirely convinced there is a bug here... I don't have your
particular situation, but on my system, cupsd runs as root, which means that
it should be able to access the device just fine, whether it's set up as lp
or usb. Is it possible that the user that you are logged in as isn't a
member of the "usb" group?
